Choose a coccus and a bacillus from the organisms you observed and calculate their surface-to-volume ratios. Consider the coccus to be a perfect sphere and the bacillus to be a cylinder. Use the equations supplied. Please show detailsThank you!
Cell Morpholgy Surface Area Volume
Coccus (S. aureus, d=1 um) SA = 4Ο2 V = 4/3 Ο3
Bacillus (E. Coli, d=1 um, h=2 um) SA = 2Ο r h + 2 Ο r2 = Ο d (r + h) V = Ο2 h
